[0034] In the prior art, when constructing a culvert, it is necessary to support the top wall of the culvert. Generally, a support trolley is set inside the culvert. A curved plate with adjustable height is installed on the support trolley. When support is needed, the telescopic structure is activated to drive the curved plate to rise, and the outer convex plate surface of the curved plate fits the inner wall surface of the culvert. Since the specifications and sizes of culverts vary, and the size and curvature of the curved plate are fixed, the support mechanism needs to be replaced when supporting culverts of different specifications, thereby increasing the use cost.

[0035] In view of this, the designer provides an automated hydraulic support device that can adjust the support area according to demand, thereby adapting to the support of culverts of different sizes, with a wide range of uses and low cost.

[0036] In this embodiment, please combine Figure 1-Figure 2 As shown, the automated hydraulic support equipment used in culvert construction includes a base 1 and a top plate 2. The base 1 is a metal plate with a rectangular structure, and the top plate 2 is a metal plate with an arc structure. The top plate 2 is arranged above the base 1. Hydraulic mechanisms 3 are fixedly installed at the four corners of the top of the base 1. A fixed plate 4 is fixedly installed at the middle position inside the top plate 2. The fixed plate 4 is a metal plate with a rectangular structure. The output ends of all hydraulic mechanisms 3 are fixedly connected to the bottom of the fixed plate 4. A plurality of reinforcing beams 5 are fixedly installed on the top of the fixed plate 4. The reinforcing beams 5 are fixedly connected to the top plate 2. The compression resistance of the top of the top plate 2 is enhanced by the setting of the reinforcing beams 5. The number of reinforcing beams 5 can be set to multiple, and it can be set as needed. In this embodiment, no specific limit is made on the number. Both sides of the top plate 2 are movably mounted with mounting shafts 6, the two mounting shafts 6 are arranged in parallel, each mounting shaft 6 is a cylindrical structure, and each mounting shaft 6 is fixedly sleeved with a movable plate 7, which is a plate with an arc structure. In order to improve the structural strength, the movable plate 7 can be set as a metal plate, which has a certain ability to recover deformation after deformation. A mounting plate 8 is fixedly mounted between the four hydraulic mechanisms 3, and the mounting plate 8 is a metal plate with a rectangular structure. A supporting mechanism is arranged on the mounting plate 8, and the supporting mechanism is used to drive the movable plate 7 to flip relative to the top plate 2 so that the movable plate 7 abuts against the inner wall surface of the culvert.

[0037] It should be understood that the mounting plate 8 can be fixed to the fixed ends of the four hydraulic mechanisms 3, or the mounting plate 8 can also be fixed to the telescopic ends of the four hydraulic mechanisms 3. For example, in this embodiment, the hydraulic mechanism 3 includes a hydraulic cylinder and a piston rod installed in the hydraulic cylinder, and the mounting plate 8 can be fixed to the four hydraulic cylinders.

[0038] like Figure 2 and Figure 3As shown, the support mechanism includes two support rods 9, a drive motor 10, a rotating shaft 11, two drive shafts 12 and three transmission bevel gears 13. The support rod 9 is a long bar with a rectangular structure. The two support rods 9 are symmetrically arranged on the top of the mounting plate 8, and the two support rods 9 are coaxially spaced. Each support rod 9 is slidably matched with the mounting plate 8, but cannot rotate relative to the mounting plate 8. The ends of the two support rods 9 that are far away are respectively used to abut against the two movable plates 7, so as to drive the movable plates 7 to turn outward. The drive motor 10 is fixedly mounted on the bottom wall of the mounting plate 8, and the rotating shaft 11 is a cylindrical structure. The rotating shaft 11 is fixedly mounted on the output end of the drive motor 10, and the rotating shaft 11 passes through the upper and lower walls of the mounting plate 8 upward. Each drive shaft 12 is a cylindrical structure with threads. The two drive shafts 12 are respectively mounted inside the two support rods 9 through threads, that is, the support rod 9 is provided with a threaded hole, and the drive shaft 12 is provided with an external thread. The drive shaft 12 is screwed into the threaded hole through its external thread. There are three transmission bevel gears 13 , which are respectively mounted on the rotating shaft 11 and the two driving shafts 12 , and are meshed for transmission. Specifically, the transmission bevel gear 13 connected to the rotating shaft 11 is meshed with the other two transmission bevel gears 13 at the same time.

[0039] It should be noted that, through the setting of the support mechanism, according to the size of the inside of the culvert, the support mechanism can be driven to squeeze the movable plate 7, so that the movable plate 7 supports the side wall of the culvert. Specifically, the drive motor 10 is started, and the drive motor 10 drives the rotating shaft 11 to rotate, and the rotating shaft 11 then drives the two driving shafts 12 to rotate through the engagement between the transmission bevel gears 13, and the driving shaft 12 is threadedly connected to the support rod 9, and the support rod 9 and the mounting plate 8 are relatively fixed in the circumferential direction of the support rod 9, that is, the support rod 9 will not rotate with the driving shaft 12, so that the support rod 9 will move relative to the mounting plate 8 in the extension direction of the support rod 9 itself, thereby squeezing the movable plate 7, and the movable plate 7 will flip outward. After flipping, it will support the side wall of the culvert according to the size of the culvert, and has a wide range of uses.

[0040] Furthermore, a protective cover 14 is fixedly installed on the mounting plate 8. The protective cover 14 is a hollow rectangular structure. The drive shaft 12 is movably installed on the side wall of the protective cover 14. The transmission bevel gear 13 is located inside the protective cover 14. The protective cover 14 can seal and protect the meshing of the transmission bevel gear 13 to avoid being affected by the external environment and extend its service life.

[0041] like Figure 1 or Figure 2As shown, in this embodiment, optionally, a moving wheel 15 is provided at the bottom of the base 1, and the moving wheel 15 can facilitate the movement of the device inside the culvert. A positioning mechanism is provided on the base 1, and the positioning mechanism can lock the support device after the support device moves to a set position, thereby improving stability during operation.

[0042] like Figure 2 and Figure 4 As shown, the positioning mechanism includes a positioning plate 16, a fixed tooth 17, a fixed seat 18, a transmission block 19 and an adjusting bolt 20. The positioning plate 16 is a rectangular plate, which is arranged at the bottom of the base 1. There are a plurality of fixed teeth 17, which are evenly distributed and fixedly installed at the bottom of the positioning plate 16. The fixed seat 18 is a hollow rectangular structure, which is fixedly installed on the top wall of the base 1. The transmission block 19 is a "T"-shaped block, which is fixedly installed on the top wall of the positioning plate 16 and located inside the fixed seat 18. The transmission block 19 and the fixed seat 18 are slidably matched. The adjusting bolt 20 is a cylindrical structure with threads, which is movably installed on the fixed seat 18. Specifically, the adjusting bolt 20 can be rotatably installed on the fixed seat 18 through a bearing, and the adjusting bolt 20 can rotate relative to the fixed seat 18, but it will not rise or fall relative to the fixed seat 18. The adjusting bolt 20 penetrates downward through the top wall of the transmission block 19 and is threadedly connected to the transmission block 19. The transmission block 19 can slide in the fixed seat 18, but it cannot rotate relative to the fixed seat 18. With this design, when the device is moved to a suitable position by the moving wheel 15, the adjusting bolt 20 can be rotated. The adjusting bolt 20 is threadedly connected to the transmission block 19, and the transmission block 19 will move inside the fixed seat 18, thereby driving the positioning plate 16 and the fixed tooth 17 to move downward. The fixed tooth 17 moves downward and is inserted into the ground, so that the device can be fixed in the current position and will not be offset during support.

[0043] Furthermore, an operating handle is installed on the adjusting bolt 20, and by applying force to the operating handle, it is convenient to rotate the adjusting bolt 20. The operating handle includes a center disk and a plurality of operating rods fixed around the center disk, and the center disk is fixed to the end of the adjusting bolt 20 by bolts, and the plurality of operating rods are arranged radially. The outer sleeve of each operating rod is connected with an anti-slip sleeve. During operation, by holding the operating rod, the force arm can be increased, and it is more convenient to rotate the adjusting bolt 20. In addition, due to the design of the anti-slip sleeve, the operator is not easy to slip when holding the anti-slip sleeve, and the force is stable.

[0044] In other embodiments, the positioning mechanism may further include a driver, which is mounted on the base 1 and is in transmission connection with the adjusting bolt 20, and is used to drive the adjusting bolt 20 to rotate. The driver may be a motor, which drives the adjusting bolt 20 to rotate, and the operation is automated, with low labor intensity and high efficiency.

[0045] The working mode of the automated hydraulic support equipment provided in this embodiment is as follows:

[0046] According to the size of the inside of the culvert, the supporting mechanism can be driven to squeeze the movable plate 7 so that the movable plate 7 supports the side wall of the culvert, and the driving motor 10 is started. The driving motor 10 drives the rotating shaft 11 to rotate, and the rotating shaft 11 then drives the two driving shafts 12 to rotate through the engagement between the transmission bevel gears 13. The driving shaft 12 is threadedly connected to the support rod 9, and the support rod 9 will move on the mounting plate 8, thereby squeezing the movable plate 7, and the movable plate 7 will flip outward. After flipping, it will support the side wall of the culvert according to the size of the culvert.

[0047] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
